While searching for lego stuff for my son I started out with a query about [lego]. Either this is a canonical issue, or good online reputation management. I do not doubt about the greatness of Lego but is this really what you think is useful for your users? Maybe it’s a better idea to use all these subdomains as sitelinks and provide some choices for your customers, so that they really are able to compare and buy some Lego.
Subdomain spam still works. Yay..
